improved MVAPerform mean and variance normalization and ARMA filtering

It's essentially the version found here, with these improvements:

  • better error reporting (e.g. failing to open file tells you so instead of core dumping)
  • more accurate mean and variance estimation (doubles instead of floats in strategic places)
  • faster computation in the case of MV (ARMA order 0)

Phonetic Transcription Tool

This tool gives the American English phonetic transcription of any string. It uses an HMM model to either generate a most likely phonetic transcription, or if a phonetic transcription is provided, it can perform forced alignment. So, it gives a reasonable pronounciation for out-of-dictionary words, or partially pronounced words.

Phonetic Transcription Tool. You can try out the demo here.

Perl scripts for parallel processing of HTK commands

Perl scripts for parallel processing of four HTK commands (HCopy, HERest, HVite, and HResults) are available.

1. HCopy.pl

2. HERest.pl

3. HVite.pl

4. HResults.pl

Those scripts use the SGE (Sun Grid Engine) for job queuing.

Detailed information about the above Perl scripts can be found here.

Brief introduction about the SGE can be found here
